Yet another Miss USA contestant has apparently sullied her tiara. Miss Nevada USA was stripped of her title Thursday after photos of her appeared on the Internet, pageant officials said.

Some of the photos show Katie Rees, 22, kissing other young women, exposing one of her breasts and pulling down her pants to show her thong underwear at a party in Tampa, Fla.

“Katie Rees has been relieved of her duties as Miss Nevada USA 2007,” said Paula M. Shugart, president of the Miss Universe Organization, which owns the Miss USA pageant and others.

Rees' dismissal came two days after Miss USA Tara Conner was allowed to keep her tiara when she agreed to go into alcohol rehab and a day after an anti-drunken-driving group cut its ties with hard-partying Miss Teen USA Katie Blair.

Rees' attorney, Mario Torres, of Tampa, defended the blonde beauty queen in a statement sent to the entertainment television show “Extra.”

“Katie Rees Miss Nevada USA wants the public to know she was 17 and had a lapse in judgment,” he said.

“The actions on that evening in subject are in no way indicative of the person she is or the person she has become. . . . She is a law-abiding citizen and talented adult. This was an isolated incident that occurred more than five years ago when she was a minor.”

Donald Trump, who co-owns Miss Universe with NBC, gave Conner, 21, a second chance after meeting with her Tuesday. Trump said Conner, who agreed to undergo drug testing, was a good person with a good heart and deserved to keep her title.

On Wednesday, Mothers Against Drunk Driving announced it was ditching Blair, the Miss Teen USA, because it was “disappointed” by news reports that the 18-year-old from Billings, Mont., had been spotted partying with Miss USA in New York clubs.

Moving out and moving on

Two blond celebs have moved into new (separate) digs to start life afresh, minus the pesky luggage of bad-boy husbands.

Oscar-winner Reese Witherspoon has left Hollywood and moved back home to Charleston, S.C., with her two children. Witherspoon announced she was separating from husband Ryan Phillippe in October, after seven years of marriage (and who knows how many of his trysts?). The couple have two children, Ava Elizabeth, 7, and Deacon, 3.

Witherspoon moved back to Charleston to be closer to her family and has enrolled both of her children in local public schools. The “Walk The Line” star recently claimed she was coping with life after the split, saying: “I'm doing fine. I'm getting out a little more now. You'll be seeing more of me.”

Britney Spears' geography didn't change quite as drastically. She is setting up housekeeping in a $7.2 million Mediterranean-style home in a gated community off Mulholland Drive in Beverly Hills. Spears, 25, has already left the Malibu mansion where she lived with her estranged husband, Kevin Federline, and their two children.

“She's moved in,” said one nearby homeowner who asked not to be identified. “She's a neighbor.” (No report on whether the homeowner broke down weeping at this point.)

The new 7,453-square-foot manse has five bedrooms, six and a half bathrooms, a pool, a media room, a library and a terrace with a view of Los Angeles. The pop star isn't the only celeb in the community. Ed McMahon lives nearby, and Gwen Stefani recently bought a house once owned by Jennifer Lopez for more than $13 million, that's just around the corner.
